Title: Substituted pyridyl-glycols and a process for the production thereof
Filed: 1958-05-22
Abstract: The invention comprises pyridyl glycols of general formula <FORM:0824554/IV (b)/1> in which R is hydrogen or a methyl group and R1 is hydrogen or an aliphatic, aromatic or heterocyclic radical, but excluding bis-(2 -pyridyl)-glycol and bis-(4-pyridyl)-glycol.  They may be prepared by heating a pyridyl glycollic acid of formula <FORM:0824554/IV (b)/2> in the presence of an aromatic, heterocyclic or aliphatic aldehyde.  Examples are given of the preparation of bis-pyridyl-(2)-glycol, monopyridyl - (2) - glycol, pyrdyl - (2) - trichlormethyl glycol, a -pyridyl-phenyl glycol, 1(pyridyl-2)-1-methyl-2-(quinolyl-2)-ethylene glycol -1,2, 1 - (pyridyl - 2) - 1 - methyl - 2 - (quinolyl - 4) - ethylene glycol - 1,2, 1 - (pyridyl - 2) - 1 - methyl - 2 - (phenyl) - ethylene glycol - 1,2, 1 - (pyridyl - 4) - 1 - methyl - 2 - phenyl - ethylene glycol - 1,2, 1 - (pyridyl - 4) - 1 - methyl - 2 - (Trichlormethyl) - ethylene glycol - 1,2, 1 - (pyridyl - 2) - 1 - methyl - 2 - (pyridyl - 4) - ethylene glycol - 1,2, and 1 - (pyridyl - 4) - 1 - methyl - 2-(pyridyl-3)-ethylene glycol-1,2.

Title: Improvements in or relating to variable speed gears and means for controlling the same
IPC: F16H57/10
Filed: 1925-06-26
Abstract: 236,545. Invernairn, (W. Beardmore), Lord, and Chorlton, A. E. L. July 7, 1924, [Convention date]. Variable-speed epicyclic gearing comprises multiple-plate clutches and brakes which are actuated in different combinations bv fluid means to effect different speeds, and which are allowed to slip to effect intermediate speeds, the invention being adapted for locomotives driven by internalcombustion engines. Control is preferably effected hydraulically through a distributing-valve. A simple form yielding solid driving and one main reduced speed is shown in Fig. 1. Planet wheels D mesh with a pinion C fast on a driving-shaft A and with a loose internally-toothed ring E. The carrier frame F of the planets is connected through a disc F<1> to a driven shaft B. Solid driving is effected by actuating a clutch 2 connecting the ring E to the disc F<1>. The main reduced speed is brought in by actuating a brake 1 connecting the ring E to a fixed casing H. Clutch and brake are engaged by means of plungers G<2> in annular chambers F<4>, G<1> to which liquid under pressure is admitted through a central pipe 2a in the one case and a fixed pipe 1<a> in the other. In a modification, a second definite reduced speed is effected bv holding the loose sun gear C by an additional brake, and connecting the ring E to the driving-shaft through an additional clutch. A four-speed gear shown in Fig. 2 comprises two simple trains arranged in series. There is a solid drive, a reduced speed through the first train, the second turning solid, then ,a different reduced speed through the second train, the first turning solid, then a doubly-reduced speed, both trains being operative, with intermediate speeds when slipping is allowed. The train on the left is like that described with reference to Fig. 1, and the driven carrier F and disc F<1> are permanently connected to the internal ring J of the other train. The carrier K<1> of the planets K of the second train is secured to the finally driven shaft B. The sun gear 6 is clutched solid by a clutch 3 or held by a brake 4. The liquid for the two clutches is supplied through concentric tubes 2<a>, 3<a>, shown also in Fig. 5. Liquid is turned with the centre of the valve P which is turned to deflect the liquid into pipes 1b - 4b.

Title: Improvements in process of cracking mineral oil
IPC: C10G9/40
Filed: 1931-06-05
Abstract: <PICT:0379759/III/1> <PICT:0379759/III/2> In cracking oils in the liquid phase under high pressure, e.g. about 80 atmospheres, the oil is maintained below but close to the critical temperature of the oil mixture throughout the reaction. The temperature is preferably raised gradually as the reaction proceeds to correspond to the gradual rise in the critical temperature.  In an example an oil having a critical temperature of 483 DEG  C. is heated first to 463 DEG  C. and then gradually to 483 DEG  C.  In order to control carefully the temperature, the oil is preferable heated indirectly by mercury or other suitable vapour, e.g. diphenyl oxide, sulphur, benzophenone, &c.  The oils are cracked by passing them serially through tubes e, Fig. 3, in three of four tanks a . . d, the remaining tank being byepassed for cleaning.  The coils e are heated by mercury vapour supplied from a boiler through a line 80 to the tanks in parallel through lines 81 provided with pressure-regulating valves and the condensed mercury is returned through clean-outs 84 having pressure-balancing columns 85 to a line 86 leading back to the boiler.  Crude oil is pumped through a line I and heat exchanger f to a surge tank g and thence through a heat exchanger h and line 4 to the cracking coils e in the tanks a . . d.  The cracked products pass through the line 10 and exchanger h to a fractionating tower i where the pressure is reduced.  The vapours are dephlegmated by gasoline pumped in through a line 15 from a tank k and pass off, through a filtering and stalilizing tower j to the condenser f and the condensate is collected in a tank k.

Title: Improvements in or relating to dental impression compositions
IPC: A61K6/90
Filed: 1931-06-08
Abstract: A plastic composition for taking dental impressions or negatives, comprises an aldehyde resin of the Wacker shellac type modified with fatty acids or a mixture of fatty acids and oils, a vegetable resin or resins and a finely divided filler.  In an example, a base of 100 parts of Wacker shellac is modified by the addition of 70 parts of a fatty acid, e.g. stearic acid or cocoa-nut oil fatty acid, or a mixture of fatty acids and olive oil, and small proportions of common resin, shellac wax and a hard brittle synthetic wax are added.  To 100 parts of the modified base are added 60 parts of copal or dammar resin previously reduced to a fine state of subdivision and treated to remove the volatile oils, e.g. by exposing to the atmosphere for a long time or by exposing to a current of hot air.  The whole is then masticated in a kneading machine, and a filler, e.g. colloidal clay, asbestos or talc in the proportion of 28 to 30 per cent of the total weight is added.  Finally the composition is passed through a heated roller mill.

A machine tool comprises a vertical column 20 along which a slide 19 carrying a double spindle head 7 is movable, said slide 19 also being rotatable about a turntable plate 18. The spindle head 7 is itself rotatable to bring either of its spindles 2 or 5 into an operative position, and into an inoperative position adjacent a tool magazine 6 where tools 1 may be removed and replaced. The spindles 2 and 5 are mounted for axial movement by hydraulic or pneumatic jacks so that they can be advanced into a tool change position adjacent the tool magazine 6, the tool gripped, the chuck on the spindle released, the spindle retracted until the tool 1 is free of the chuck, the tool 1 removed and replaced by a fresh tool, and the spindle advanced on to the new tool to grip it in its chuck before the spindle head 7 is rotated to place the fresh tool in an operating position. The hydraulic or pneumatic jacks are also used to hold the spindles against a drive coupling when in the operative position. The tool magazine 6 comprises clips (22), (Fig. 5, not shown) for holding a ring of tools, and a slide (21) having gripping means (14) for picking off a tool 1 and presenting it in alignment with the spindle in the inoperative position.

Title: Process for the polycondensation of the ethylene glycol diester of terephthalic acidin the molten state
IPC: C08G63/81
Filed: 1956-06-04
Abstract: Polyethylene terephthalate is made by poly-condensing the ethylene glycol diester of terephthalic acid in the molten state and bringing the melt into intimate contact with the vapour of a paraffin hydrocarbon or an aromatic or cycloaliphatic compound which contains no functional group, the vapour being at 250-320 DEG  C.  The vapour may be that of undecane or its homologues, benzene, toluene, xylene or cyclohexane.  In a batch process, a current of the vapour is passed through the melt whilst in a continuous process a current of the melt in finely divided form is passed in counter-current to a current of the vapour.  In an example, dimethyl terephthalate is trans-esterified with ethylene glycol in presence of a zinc oxide-boron trioxide catalyst and the resulting bis glycol ester heated to 250 DEG  C. whilst passing a current of benzene vapour at 280 DEG  C. through the melt.  The azeotropic mixture of ethylene glycol and benzene which distils off is passed through an adsorption column and the benzene is returned to the reaction vessel after being reheated.
